Subject: [PATCH v7 5/6] zsmalloc: Add zpool_ops field to zs_pool to store evict handlers
Date: Mon, 28 Nov 2022 11:16:14 -0800 [thread overview]
Message-ID: <20221128191616.1261026-6-nphamcs@gmail.com> (raw)
In-Reply-To: <20221128191616.1261026-1-nphamcs@gmail.com>
This adds a new field to zs_pool to store evict handlers for writeback,
analogous to the zbud allocator.
